The Littelfuse 0481001.HXESD is a 1A indicating fuse from the 481 Series, designed for overcurrent protection in telecom applications. It is rated for 125VAC and 125VDC with a fast-blow response time. The fuse offers a breaking capacity of 300A at rated voltage (125VAC/125VDC) and 450A at 60VDC. It operates over a temperature range of -55°C to 125°C.
The fuse body is constructed from polyphenylene sulfide with a UL 94 V-0 flammability rating, and the contacts are made of bright alloy-plated beryllium copper. The package style is an alarm indicator, requiring a separate holder for installation. Physical dimensions are 16.90mm length, 5.80mm width, and 19.60mm height. The body color is gray, with color-coded indicator flags for ampere rating identification.
Key electrical characteristics include a nominal cold resistance of 0.665 Ohms and a melting I²t of 1.82 A²s. This component is CSA and UR approved. It is designed for use in telecom equipment and other applications where visual indication of an open fuse is beneficial.
